Comment
If voltage (e.g. 230 VAC) is passed
through the alarm relay, the SELV signal
wires lose their property of reinforced
insulation, meaning they then have only
basic insulation
The SELV property (reinforced
insulation) is not lost when voltages of up
to 110 VDC are passed through the
alarm relay.
; Use the device in accordance with its degree of protection.
Information on surface quality
The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may change during the production period.
This has no effect on strength, dimensional stability and dimensional
accuracy.
The color pigments in the paints used perceptibly react to UV light over
the course of time. The product is to be protected against UV radiation to
prevent the formation of patches and fading. Changes in color are not a
reason for complaint and are not covered by the warranty. UV radiation
in the frequency range and the intensity of natural solar radiation has no
effect on the technical properties of the products.
3.5 Mounting data
Any further mounting data required can be taken from the product
drawing or Section Chapter 4.1 Mechanical connection.

Operating instructions
4. CONNECTION AND STARTUP
4.1 Mechanical connection
; The fan may not be handled in the area around the inlet nozzle during
transport and installation.
There is a risk of damage to the impeller.
; Check the device for transport damage. Damaged devices are not to
be installed.
; Install the undamaged device in accordance with your application.
The fan must not be strained on fastening.
●
4.2 Electrical connection
CAUTION
Risk of cutting and crushing when removing device
from packaging
→ Carefully remove the device from the packaging by grasping
hold of the frame. Never subject to any impact.
→ Wear safety shoes and cut-resistant safety gloves.
NOTE
Damage to the device from vibration
Bearing damage, shorter service life
→ The fan must not be subjected to force or excessive vibration
from sections of the installation.
→ It is advisable to use spring or rubber isolators for
decoupling (not included in scope of delivery). The fan is to
be operated sufficiently far away from the resonant frequency
of the vibration isolators.
→ If the fan is connected to air ducts, the connection should
be isolated from vibration, e.g. using compensators or similar
elements.
→ Ensure stress-free attachment of the fan to the sub-
structure.
CAUTION
Possible damage to the device
If the device slips during installation, serious damage can result.
→ Ensure that the device is securely positioned at its place of
installation until all fastening screws have been tightened.
DANGER
Faulty insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
regulations for voltage, current, insulation material, capacity,
etc.
→ Route cables so that they cannot be touched by any
rotating parts.
DANGER
Electrical charge (>50 µC) between phase conductor and
protective earth connection after switching off supply
with multiple devices connected in parallel.
Electric shock, risk of injury
→ Ensure sufficient protection against accidental contact.
Before working on the electrical hookup, short the supply
and PE connections.
